Machubu opangidwa ndi PVC ndi osakaniza apadera a polyvinyl chloride (PVC) ndi zowonjezera zina zomwe zimapangidwira kupanga machubu a malata.Machubu a corrugated, omwe amadziwikanso kuti mapaipi opangidwa ndi malata kapena ma flexible conduits, amagwiritsidwa ntchito m'mafakitale osiyanasiyana pofuna kuteteza chingwe, kasamalidwe ka waya, ndi ntchito zotumizira madzimadzi.Mapangidwe a PVC omwe amagwiritsidwa ntchito pazitsulo zowonongeka amapangidwa kuti apereke zinthu zenizeni komanso makhalidwe abwino.Mankhwalawa amakhala osinthika kwambiri, omwe amalola machubu kukhala opindika mosavuta ndikusintha popanda kuwononga kapena kusokoneza kukhulupirika kwawo.Kusinthasintha kwa mankhwala a PVC kumathandizanso kuyika mosavuta ndi kuyendayenda m'malo ovuta kapena ochepa.Izi zimatsimikizira kuti machubu amatha kupirira zovuta za ntchito zosiyanasiyana, monga kupsinjika kwamakina, kukhudzidwa, ndi zinthu zachilengedwe.Kuonjezera apo, mankhwala a PVC a machubu a corrugated nthawi zambiri amaphatikizapo zowonjezera zowonjezera kuti apititse patsogolo zinthu zina zofunika.Mwachitsanzo, zolimbitsa thupi za UV zitha kuphatikizidwa kuti ziteteze machubu ku kuwonongeka kwa kuwala kwa dzuwa kapena magwero ena a UV.Mafuta oletsa moto amathanso kuwonjezeredwa kuti apititse patsogolo kukana kwa moto kwa machubu a malata.Kupanga ndi kukonza machubu a PVC opangidwa ndi malata nthawi zambiri amachitidwa pansi pazikhalidwe zoyendetsedwa bwino kuti zitsimikizire kuti zinthu zili bwino.Mankhwalawa amaperekedwa mumtundu wa pellet kapena ufa, womwe umatha kutulutsidwa kapena kupangidwa kukhala machubu opangidwa ndi malata pogwiritsa ntchito zida zapadera. Ndizofunikira kudziwa kuti kugwiritsa ntchito PVC ndi zowonjezera zina mumagulu apulasitiki kwadzetsa nkhawa zachilengedwe komanso thanzi.Mankhwala ena a PVC amatha kukhala ndi zowonjezera monga phthalates, zomwe zakhala zikuyang'aniridwa ndi malamulo chifukwa cha kuopsa kwa thanzi lawo.Kuti athane ndi nkhawazi, opanga akufufuza mochulukirachulukira zida zina ndi zowonjezera kuti apange njira zokhazikika zamalati.Pafupifupi, machubu a PVC opangidwa ndi malata amapangidwa kuti apereke kusinthasintha, mphamvu, ndi kulimba kwa ntchito zosiyanasiyana.Komabe, ndikofunikira kuganizira ndikuthana ndi zovuta zilizonse zachilengedwe kapena zaumoyo zokhudzana ndi kugwiritsa ntchito PVC ndi zowonjezera zake popanga.
